Replacement of the HD for more capacity and more drive
5 - 15 minutes
After loading Yosemite and more and more documents and programs the imac mid 2010 worked in some parts to slow and with irregularities. So in a first step I doubled the RAM from 4 to 8 GB. The actual next step was to increase the storage capacity from a 0.5 HD to a 2 TB SSD Hybrid 3.5".
I worked me through - would say the best. Aside my laptop with the super guide in front - and the fine helper hands of my wife...because the cable connectors are to small for big fingers. I helped me too with a little tool. Surprised I was when despite of much care the "display data connection cable" came away itself because this cable is a little stiff. I really took care by opening the display board! The sense of the plastic pull tab there I didn't understand really. The LCD thermal sensor connection cable was taped to the fan case. (I didn't tape it again when I built all together). The "display data connection cable" I could plug in again by patience.
In any case: After 2 hours the imac was fitted again together and works now since one week perfect, will say in his "old youth".
